y = 2√x-25-5
y = fx-25 +5
y = + 1+25 – 5
y = f(x+25 +5

Answers

=Y2-10Y

We move all terms to the left:

-(Y2-10Y)=0

We add all the numbers together, and all the variables

-(+Y^2-10Y)=0

We get rid of parentheses

-Y^2+10Y=0

We add all the numbers together, and all the variables

The inverse of the given function is y=±√(x+25)+5. Therefore, the option D is the correct answer.

What is inverse function?

Inverse function is represented by f⁻¹ with regards to the original function  and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.

The given function is y=x²-10x

Replace x with y and y with x.

x=y²-10y

x=y(y-10)

y=x/(y-10)

So, the equation is non-invertible, the equations of the graph gained by reflecting over y = x

y=±√(x+25)+5

Therefore, the option D is the correct answer.

Write the equation of the line that passes through the points (1,6) and (3, -4)

A. y = -5x + 11

B. y = x - 11

C. y = 5x +3

D. y = 2x -3

Answers

Answer:

A. y = -5x + 11

Step-by-step explanation:

The general form of the equation of a line is given as

y - y1 = m (x - x1)

where m is the slope and x1, y1 are the coordinates of a point on the line.

m = (y2 - y1)/(x2 - x1)

Given the points (1,6) and (3, -4)

m = (-4-6)/(3-1)

=-10/2

= -5

The equation of the line will be

y - 6 = -5(x -1)

y - 6 = -5x + 5

Add 6 to both side

y = -5x + 5 + 6

y = -5x + 11

Answers

Answer:

The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y-value of the point where the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope.

Which of the decimals or fractions is not equal to 0.525 or 1/8

Answers

Answer:

0.18

Step-by-step explanation:

1/8 as a decimal is 0.125

1/8 un-simplified is 3/24

0.525 as a fraction is 21/40

So 0.18 is the only one that doesn't belong

0.18 is not equal to 0.525 or 1/8. Therefore Option (A) is the correct answer.

We need to find which of the decimals or fractions are not equal to 0.525 or 1/8.

How do convert decimals to fractions?

The decimal numeral system is the standard system for denoting integer and non-integer numbers.

To convert decimal to fraction follow these steps

Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number).

Step 2: Remove the decimal places by multiplication. First, count how many places are to the right of the decimal. Next, given that you have x decimal places, multiply the numerator and denominator by [tex]10^{x}[/tex].

Step 3: Reduce the fraction. Find the Greatest Common Factor (GCF) of the numerator and denominator and divide both numerator and denominator by the GCF.

Step 4: Simplify the remaining fraction to a mixed number fraction if possible.

Now, from option (A)

0.18=18/100=9/25

From option (B)

0.125=125/1000=5/40=1/8

From option (C)

3/24=1/8

From option (D)

21/40=0.525

Therefore, option (A) is the correct answer.

141.12 cm^2

Step-by-step explanation:

The formula for area of a triangle is [tex]h(b1+b2)1/2[/tex]. you have that:

b1, or base 1, = 12.2

b2, or base 2, = 10.2

h, or height, = 12.6

so plug this into the formula:

[tex]12.6(12.2+10.2)1/2\\12.6(22.4)1/2\\12.6*11.2\\141.12[/tex]

Answer:

141.12cm^2

Step-by-step explanation:

First split the trapezoid into two shapes: a rectangle and a triangle.

The area of the rectangle is (10.2cm)(12.6cm) = 128.52cm^2

Finding the area of the triangle is a little trickier. In order to find the base of the triangle, subtract 12.2-10.2=2. The area of a triangle is defined as A=1/2bh, so let's plug in our values:

A = (1/2)(2)(12.6) = 12.6cm^2

Now, add them together.

12.6cm^2 + 128.52cm^2 = 141.12cm^2

plot 2 2/3 and 1 7/9.

Answers

Answer:

Down below :)

Step-by-step explanation:

Hey there!

To plot a fraction on a graph you have to turn it into an improper fraction. In this case, the improper fraction for 2 2/3 is 8/3 and the improper fraction for 1 7/9 is 16/9.

*Note: To find the improper fraction of a fraction you must multiply the denominator by the whole number and then add the numerator.

With these two improper fractions...

8/3

16/9 (Simplify it down to 8/3 since both 16 and 9 go into 3)

You can now graph it. To graph, the numerator tells you how many times to go up and the denominator tells you how many times to go right. IF IT'S NEGATIVE IT WILL DO THE OPPOSITE IF THE NUMERATOR IS NEGATIVE IT WILL GO DOWN INSTEAD OF UP AND IF THE DENOMINATOR IS NEGATIVE IT WILL GO LEFT INSTEAD OF RIGHT.

8/9 means you need to start at the origin, (0,0) and go 8 up and 3 to the right. 8/3 means you start at the origin and go 8 up and 3 to the right. You will almost always start at the origin.

Is the point (3, 4) a solution to the linear equation 5x - 9y = 32?

Answers

Answer:

it equals -21 so no

Step-by-step explanation:

happy valentines!

Answer:

No, It does not.

Step-by-step explanation:

(3,4) means (x,y). When you insert 3 to x and 4 to y, You get this:

5(3)-9(4)=32

If you multiply 5 and 3, You get 15.

15-9(4)=32

If you multiply 9 and 4, you get 36.

15-36=32

If you subtract 15-36, you get -21.

This is why the answer is no because -21 does not equal 32

-21 ≠ 32

Hope this helps! :)

What is the measure of the missing angle

Answers

119 I believe since a straight angle sums up to 180

The measure of the missing angle is 119 degrees.

Explanation:

This is because this angle is a supplementary angle, which means that two angles put together equal 180 degrees. Since we already know the measure of one angle (61 degrees), we can subtract it from 180 degrees. We could figure this out by doing 180-61, which would get us the measure of the missing angle, 119 degrees.

Education in modelled in the Interest of the industrial age and in the image of it. Said at a interview once Ken Robinson.Problem 1: Industrial age valuesAll day long students do nothing but follow instructions but, sit down, take out you books, go to problem number 3, stop talking. At school your award for doing exactly what you do. These are the same rules for industry workers. How far can you go in the real world by that rule? The real world respects people how can be creative, communicate their ideas, and collaborate with others. But we don't get to developpe suck skills in a system that's based on industry values. Problem 2: Lack of autonomyAt school kids can not control what they learn the system controls what you learn, But in today's world you like to do what you do. You do it causes you want to. You manage your own time. While making your own designs, regarding want to do it, and when to do it. But life at school looks very different, that kids are not incontrol of their own lifes. They just follow what ever is to be done. Not making their own lifes. Expert believe Anthony is incredibly important for children. It's no wonder how there always bored and don't like school. Children don't like school because in school they are not free. Says Peter gray. Can u imagine how you would feel if you were told exactly what to do for every minute of your life?Problem 3: Inauthentic meaningMost of the learning in not authentic causes it relies on memorization, and rote learning. The system makes all kids must know what they're learning. And then every few months we retained by administering exams. WE know this is not authentic causes most of it is gone the day after the exam. It can be so much more than just memorization, and retention. But that's the only thing we musser, and test scores is the only thing we value. This has created a very unhealthy culture for students, parents, and teachers. Children are going through endless hours of learning. Staying up all night memorizing ulsee facts that they will forget very soon. Problem 4: No room for passionWe have a very strict rule, where each child must learn the same thing at the same time, in the same way as everyone else. This doesn't respect the basic fact for being a human, that each of us is unique and different in our own way. We all have different passions and interest. Life today is to find our passion. But does school find or develop their passion? There is no room to ever say, What am i good at? What do i want to do in life? How do I fit in this world? But the system doesn't seem to care. There are so many greatly tall people how failed in the tradition schools. Had a average grade of C in school By Winston churchill. Failed 6th grade Said Steven spielberg.

Problem 5: Difference in how we learn All of us in also different in how we learn, in how much time we take to learn something, and what tools and records work best for us. But the system has no room for such differences. So if you a bit slow in learning something you are considered a failure. When all you ended was a bit of time to catch up. Problem 6: LecturingIn the current system children are lecuterd more than 5 hours a day. But there are a few big probes with all that. In the class different students are at different levels in how much of understanding they are in. Whatever class your in there are bond to be students who are bored because there ahead, or confused causes there behind. Now thanks to internet , and digital media, kids have at their fingertips all the information in the world. Technology has made it possible for anyone to learn anything. But for fear on losing control the system is not alloy for you to use these incredible resources! Our system of school with evolved in the induslaty age, has become outdated, and ineffective. If we want to prepare kids for the modern day world, if we want leaning to be effective and engaging, then there's no doubt we need to fundamentally change our system of education.
